Ground is supplied:
^ to smart entrance control unit terminal (10)
^ through body grounds (M43), (M44) and (M60).
THEFT WARNING SYSTEM ACTIVATION (Without key or remote controller used to lock doors)
The operation of the theft warning system is controlled by the doors, hood and trunk lid.
To activate the theft warning system, the ignition key must be removed, doors, hood and trunk closed,and the doors locked.
When a door is open, smart entrance control unit terminal (16) receives a ground signal from door switches.
Wen a door is unlocked, smart entrance control unit terminal (12), (13) or (14) receives a ground signal:
^ from terminal (4) of all the door unlock sensors
^ through body grounds (M43), (M44) and (M60).
When the hood is open, smart entrance control unit terminal (29) receives a ground signal:
^ from terminal (1) of the hood switch
^ through body grounds (E13) and (E25).
When the trunk lid is open, smart entrance control unit terminal (26) receives a ground signal:
^ from terminal (1) of the trunk room lamp switch
^ through body grounds (T9) and (T10).
If none of the described conditions exist, the theft warning system will activate automatically.
THEFT WARNING SYSTEM ACTIVATION (With key or remote controller used to lock doors)
If the key or remote controller is used to lock doors, terminal receives a ground signal:
^ from terminal (1) of the door key cylinder switch LH
^ from terminal (2) of the door key cylinder switch RH
^ through body grounds (M43),(M44) and (M60).
If this signal is received by the smart entrance control unit, the theft warning system will activate automatically.
With the theft warning system activated, smart entrance control unit terminal (33) supplies ground to of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then go out.
THEFT WARNING SYSTEM OPERATION
The theft warning system is triggered by:
^ opening a door or the trunk lid without using the key
^ opening the hood
^ tampering with the key cylinder in the door.
Once the theft warning system has been activated, it will be triggered if the smart entrance control unit receives a ground signal at terminal (15), (16), (26) or (29). Also, when a door key tamper signal is received at the smart entrance control unit, the system will be triggered. The head lamps flash and the horn sounds intermittently, and the starting system is interrupted.
When a door key cylinder switch has been tampered with, smart entrance control unit terminal (28) receives a ground signal:
^ from terminal (3) of the front LH or RH key cylinder switch
^ through body grounds (M43), (M44) and (M60).
If the theft warning system is triggered, ground is supplied:
^ from terminal (32) of the smart entrance control unit
^ to theft warning relay terminal (2).
With power and ground supplied, power to the clutch interlock relay (M/T models for U.S.A.), inhibitor relay (A/T models) or starter motor (M/T models for Canada) is interrupted. The starter motor will not crank and the engine will not start.
When the theft warning system is triggered, ground is supplied intermittently:
^ from terminal (8) of the smart entrance control unit
^ to theft warning lamp relay terminal (2) and
^ to horn relay-2 terminal (2) .
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate if the vehicle is tampered with again.
THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door or the trunk lid must be unlocked with the key or remote controller.
When the key is used to unlock a door, smart entrance control unit terminal (31) receives a ground signal
^ from terminal (2) of the LH key cylinder switch
^ from terminal (1) of the RH key cylinder switch.
When the key is used to unlock the trunk lid, smart entrance control unit terminal (27) receives a ground signal from terminal (1) of the trunk key cylinder switch.
When the smart entrance control unit receives either one of these signals, the theft warning system is deactivated.
PANIC ALARM OPERATION
Multi-remote control system may or may not operate theft warning system (horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently:
^ from smart entrance control unit terminal (8)
^ to theft warning lamp relay terminal (2) and
^ to horn relay-2 terminal (2).
The headlamp flashes and the horn sounds intermittently:
The alarm automatically turns off after 30 seconds or when smart entrance control unit receives any signal from multi-remote controller.
